California as a wine producing region has grown in size and importance considerably over the past couple of centuries, and today is the proud producer of more than ninety percent of the United States' wines. Indeed, if California was a country, it would be the fourth largest producer of wine in the world, with a vast range of vineyards covering almost half a million acres. The secret to California's success as a wine region has a lot to do with the high quality of its soils, and the fact that it has an extensive Pacific coastline which perfectly tempers the blazing sunshine it experiences all year round. The winds coming off the ocean cool the vines, and the natural valleys and mountainsides which make up most of the state's wine regions make for ideal areas in which to cultivate a variety of high quality grapes. Semillon was, at one point not so long ago, widely believed to be one of the most grown grape varietals in the world. Whilst today the numbers of Semillon grapes has dropped considerably, it remains a widely planted grape with vineyards all over Europe and the New World dedicated to making the most of this special and flavorful varietal. The grapes are recognizable by their golden color, and the fact that they can take on a pinkish hue in particularly warm climates. The wines the Semillon grape produces are notably varied, and are often very crisp and dry, or sweet and soft, full of a wide range of flavors Commonly, dry Semillon wines are particularly citrus in flavor, with a delicate and summery bouquet. The vine is hardy and vigorous, and notable for being easy to grow and produce high yields from.
